NATO military is divided into two commands, Atlantic and Europe. Each has a Supreme Allied Commander as highest ranking military officer. They were known as Supreme Allied Commander Atlantic (SACLANT) and Supreme Allied Commander Europe (SACEUR).
In practice, SACEUR is also Commander, United States European Command (CDRUSEUCOM), although the two roles may have conflicting interests.
In June 2003 the SACLANT organisation was decomissioned and Allied Command Transformation was established. This is a transitory command, intended to reshape the NATO command structure to respond to rapidly changing world situations and technology. The commander of the new organisation is Admiral Edmund P. Giambastiani, Jr., U.S. Navy. The headquarters of ACT is at the old SACLANT headquarters in Norfolk, Virginia, USA.
